  • INQUIRY

The service temperature for Corundum Bricks can reach up to 1800°C. Corundum Bricks can be used in nearly all fields of industrial application where extreme high temperature and increased resistance against aggressive slags and atmospheres are necessary. Such properties or features of Corundum Bricks are necessary especially in the chemical industry and for the production of carbon black. The addition of chromium oxide, zirconium oxide, and phosphates gives the bricks excellent structural flexibility, which is required for ash melting furnaces and gas reactors in incinerators.

Corundum bricks with a 99 % Al₂O₃content are also resistant at high operating temperatures in CO atmoshperes and hydrogenous atmospheres. They are used in furnaces for the chemical and petrochemical industry under strongly reducing conditions.

Main mineral component of corundum brick is corundum phase, it has excellent physical property in high temperature, resistance to chemical corrosion. It is widely used in lining of ovens of petrochemical industry; bottom of steel rolling mill and in the second-stage converters of the  ammonia synthesis furnaces, steel notch.

Application:

In steel industry, corundum based products have double service life compared with ceramic based products such as ladle air brick. In nonferrous metal industry, corundum brick has better  performance on abrasion and corrosion resistance compared with other fire brick. What's more, corundum bricks also have good performance in casting, glass, druss , oil and other high temperature indutries.
